Attached are HV5122 and Z570M series parts for Diptrace. The HV5122 pattern
is a PLC44 socket. Both were made from existing parts. I have no idea how
close there are, but sooner or later I'll find out. The nixie pattern is
one layer. I'm not sure if that's the best way to do it.

I actually designed and built a FLW clock out of IV-4/IV-17s; they’re quite
nice little tubes and currently still reasonably easy to get on the e-site.

And here’s a short movie of an older version of the clock “walking the
tree” as was
Very nice... I have bought 10 IV-4's just for this kind of thing.
If you decide to go open please share.
BTW... which processor are you using?

IN-12a and IN-12b both have upside down 2 and 5s, the only difference is
the digit dots on them. They are Russians, aimed for efficiency, so no.

That totally worked! but I did the wiring when the 170v is on, and got
zapped, threw my only 220k ohm to nowhere. DAW

I've got a bunch of IV-4s and IV-17s, so I'm definitely interested. Count
me in once you open it up. TIA

I suggest you add a power-on indicator; it only requires a few milliwatts
and it could save your life.
Also, it's wise to put a large resistor across each DC supply to discharge
the capacitors, especially the HV ones, when the power is off. Nixies will
extinguish around 120-150V, so just
